Hint: Our forefathers would spend hours boiling food over smokey wood fires, but now we only need to push a few buttons and toss stuff into a microwave oven, and our meal is doing in a minute or two. In a microwave oven, food is heated by microwaves. They are rapid and efficient because the heat is directed directly to the food molecules. Let us study microwaves and their wavelength range.
Complete answer:
Microwaves are electromagnetic waves with frequencies ranging from \[300\] MHz to \[300\] GHz, and wavelengths range from \[1\] mm to rough \[30\] cm. Microwaves are the conventional name for microwave radiation. In the electromagnetic spectrum, they are located between infrared and radio waves.
Microwaves are electromagnetic waves with frequencies ranging from \[1\] gigahertz to \[1\] terahertz \[\left( {{{10}^9}-{{10}^{12}}} \right)\] cycles per second) with wavelengths ranging from \[1\] mm to \[1\] m.
Additional information:
Microwaves have the following characteristics:
Microwaves reflected off metal surfaces. Microwaves of a specific wavelength travel through the earth's atmosphere and can be used to send data to and from orbiting satellites. As a result, metal satellite dishes are used because they reflect microwaves well.
Water absorbs various frequencies of microwaves. Microwaves have this characteristic, which is beneficial in the kitchen. Microwaves are absorbed by water in food, causing the water to heat up and cook the food.
Wave effects such as refraction, reflection, interference, and diffraction affect microwave transmission.
Microwaves can penetrate glass and plastic. This is why, in a microwave oven, we use plastic or glass containers rather than metal canisters, as metal reflects microwaves.
Note:
Microwaves have similar applications to radio waves. They're employed in communications, radio astronomy, remote sensing, radar, and, of course, cooking because of their heating capabilities. Microwaves are used in cell phones because microwaves can be created with small antennas, mobile phones do not need to be huge.
